Y and which may be cheaply manufactured- For1 further comprehension'of the invention, and of the objects and advantages therjeof, reference'will be had tothe followingdescription and4 accompanying drawing, I and tothe appended claims in which the various novel features of the invention are more .pan ticularly set forth.'

Fig. 1 of the drawing is a sideelevationa'l,

. view of my improved device.

Fig. 2 is an enlarged fragmentary View of one of the cutting lmembers taken on the plane indicated by the line 2 2.

Fig. 3 is a similarview of the other cutting member taken on a plane indicated by the Apiane 3-3. p

Fig. 4 is an end view of theV cutting member shown in Figure 2 taken on a plane indicated bythe line 4-4 of Fig. 1.

Fig. 5 is a similar view of the cutting member shown in Figure 3 taken on a plane indicated by the line 5 5 of Fig. 1.

As here embodied my improved device comprises a jaw member 10 having a suitable handle 11 and a similar jaw member 12 having fa similar handle 13, the said jaw members 10 and 11 being pivotally attached to one another as designated by the numeral 14 on the accompanying drawing, the heretobefore mentioned construction being such as will permit of manipulation, opening and closing similar to that of a pair of scissors or pliers. The jaw member 10 is provided with a pointed protruding member 15, at or near the extremity of the j aw member 10 and'at right angles thereto. The other jaw member 12 is provided with suitable aperture 16, so located that the jaw .members 10 and 12 may be closed, the pointed pr0truding member entering the aperture 16.

The Skinning and cutting member `17 is at right angles to the jaw member 10, preferably formed thereon by turning inwards a portion of the edge portion of the member 10, the said skinning and cutting member 17 having a V shaped or notched portion 18, and

a beveled edge 19, such as ordinarily usedY for cutting. The jaw member 12 1s provided with a similar skinning and cutting member 2O atright angles' to the jaw niember 12,-preferably formedthereon by turning inwards a portion of the edge portion of the jaw member 12, the said Skinning 'and cutting "inember 20 having a vsimilar V shaped-ornotched'` portion 21 'and' a similar beveled edge 22 as heretobefore described.

'Ihe said Skinning and cutting member 20 is also' provided with anfeXtendedf portion 23'having a beveled edge24, adapted to be used-as hereinafter setV forth for scrapwire. v

In the operation ormanipulat-ion of lmyn improved device, by means of thev pointed ing remaining insulation "material from.. the v I protruding member 15 it 'is obvious. that braided `wire may be readily separated,`g.and

that the insulation may be readilycut 'by means of the two notchedE portions .18 and 21, a screw'25, such as a thumb screworset screw, or any similar threaded screw, suitably threaded. into one of the handles 11 or 13, as shown on the accompanying drawing,

so as toset the distance between the twoA notched portions 18 and 21, when the device is closed, to accommodate'various gages ofwires, so that the notched portions 18 and 21 will not cut the wire, the insulation having been cut as heretobefore described, by pulllation may bereadily removed or skinned,

and by turning back the screw 25 so as to perin the direction ofthe handle ends of theV pliers while the latter are urged forwardly or held substantially at rest.A This operation may be accomplished by inserting the proj ection 15 between the braided wires in advance of their ends so as to leave a portion o-f wire 100 suihciently long to provide a grip.,

The end of cutting member 17 is provided with a partially beveled edge 18 adapted to register with aflat end portion of the cut-y Y This sharpened beveled.

ting member 20. edge may be employed for cutting barewire when such wire is disposed between the same Vand the fiat portion of the member 20.

It is further obvious that by means of the beveled edge 24 of the extended vportion 23V that the said wire may be scraped, solas to remove any particles of insulation'that have remained.

`ing the device along the wire, the said insu- Y may vvillhe understood that :improved-Vde-` {VCG maybemde of'any"materials,` such as Vordinarilyv used fondevices of l this nature.

f lWhile I have above described the preferredl .f orxn,v `construction and Varrangementv of the .several elements employed,` itjvvillhe "rinden Q `stood that thedevice isgnevertheless, suscepti-y ble of considerable modification therein, and Itherefor'e reserve theprivll'ege of resorting vto all sucfhchanges asma7 betfairly embodied within the spirita-nd scopeA of the invention asclairned.
